GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 422,947', dated March 11, 1890. i Application filed March 30, 1889. i Serial N0. 305,478. (No model.)

To all whom it may concern:

Be it known that I, EDWIN M. KELLOGG, a citizen of the United States,'residing at Dela- Van, in the county of Valworth, State of Wis- V cousin, have invented certain new and useful Improvements in Grain -Binders, of which the following is a specification.

In that type of grain binders generally known as the Appleby, and most frequently To used nowadays, the tripping-clutch has been, as a rule, located uponthe end of the cranked packer-shaft and acted upon by a more or less complicated train of communicating parts A from the compressor finger or fingers, the packer-shaft itself, by which may also be understood the trip-clutch shaft, extending from front to rear of the machine inside of the subtending arm of the post-frame. Y

In the present invention a short packershaft is employed of just sufficient length to drive the packers, While the clutch-shaft is located outside of in close proximity to and parallel with the subtending arm of the postframe or with the outer tubular bar of the binder-frame, and the trip-clutch is immediately beneath the compressing-finger and acted upon directly by a latch which forms a rigid heel-extension of that finger. The main binder gear is driven by a chain from a 3o sprocket at one end of this clutch shaft, and the compressing and tripping finger is mounted upon a rock-shaft in such manner that it can yield a short distance without disturbing the shaft, and is thrown open at the 3 5 proper moment and reset byalink connected at its lower end with a crank upon the shaft and at its upper end with a lever acted upon by a cam on said main gear. The binderarm is formed with an el astically-yieldin g section in its shank opposite to the compressing and tripping finger, and certain improvements are introduced into the knotting, cutting, and holding head, all as will presently appear.

In the drawings, Figure l is a top plan View of so much of an automatic grain-binder embodying my invention-as is necessary to an understanding thereof, the overhanging arm of the post-frame and the grain-deck being removed. Fig. 2 is an elevation from the 5o stubble side of the machine, the grain-deck being omitted. Fig. Sis a rear elevation with l the mode of presenting the cord.

the front part of the grain-deck shown. Fig.

4: is a vertical section on a line parallel with but slightly in rear of the plane in which the binder-arm plays, except as to the knotting- 5 5 hea'd, which is omitted. Fig. 5 is a front elevation with the graindeek omitted. Figs. 6 and 7 are enlarged details of the tripping device, the first seen from the top and the second from the stubble side of the machine, and 6o suitably broken away to more clearly expose the construction of the parts. Fig'S is also an enlarged detail of the tripping device seen from the rear. Fig. 9 is a rear elevation of. the knotting-head with the tyer-cam and a portion of the binder-arm shown to explain Fig. l0 is an elevation, partly in section from the stub ble side, of said knotting, cutting, and holding head; and Fig. 11 is an enlarged detail of 7o a portion of the breast-plate with the holder in its proper relative position thereto seen from the top.

A represents the post-frame of the binder, having an upper overhanging tubular arm a, which supports the tyer-shaft, and a lower subtending arm d', upon which is mounted the binder-arm shaft. The subtending arm is bolted to transverse bars or brackets B, in which are formed bearings for the longitudi- -nal shafts of the machine, with the exception A of the two just named, and these brackets are united at their inner ends by a longitudinal tubular frame-bar C, and near the outer ends, beneath the post-'frame and slightly outside 85 of itssubtending arm,by a second longitudinal frame-bar C, which, however, is herein shown as having a downward bend or curve c immediately beneath the compressing-iinger to make room for certain of the tripping 9o agencies, but would notnecessarily have this curve if somewhat differently located.

In bearings d in the two rear transverse frame-bars, or those between which the binder-arm plays, is mounted a short cranked o 5 packer-shaft D, bearing brackets D', the heel ends of which are supported by links d', of which the front link is, for convenience, sleeved upon the shaft Which carries the tripping-clutch, and which will hereinafter be roo termed the driving-shaf t or clutch-shaft, while the rear link is sleeved upon a section.

of the rock-shaft which carries the compressing finger' or lingers and which lies somewhat above the driving-shaft, as will be presently explained.

The packershaftis to receive motion from the harvester, and for that purpose is provided, when the binder is adjustable back and forth, with a telescoping section cl2, and will in turn communicate motion, by means of a pinion D2, to a gear E, mounted upon a short stub-axle e, secured to the rear transverse frame-bar, and alongside this gear and rigid therewith, so as to turn with it' when it is driven, is a sprocket-wheel E', communieating by a chain e with an opposing sprocket-wheel E2, keyed to the rear end of a short shaft-section E3, mounted in a bearing @zoutside of the subtending arm from the postframe parallel therewith, and below the support for the compressing-finger. This shaftsection abuts against a second shaft-section E4, and has its end, for steadiness, embraced by a sleeve e3, pinned to said forward section. The rearsection has also pinned to it just at the end of this sleeve a cross-head F, carrying lugs -or rollers f, such as usual in the tripping-clutch of the Appleby binder, and the Afront section likewise carries most conveniently as a part of the sleeve a second crosshead F', one arm of which bears a pivoted dog F2, having flanges or lugs f and f2 on opposite sides of its nose and out of line with each other,intended to be caught alternately, the iirst by the driving-lugs on the opposite section ofthe clutch and the second by the trip-latch, and the other arm bears a spring f3, by which the dog is urged normally into v the path of the driving-lugs 'and carried therein whenever released by the trip-latch. The details of this clutch may of course bek somewhat varied, but the form 'j ust described is the one that at' present seems lnost advisits forward end, by a chai-ny, and sprocketteeth formed on the periphery of the main gear and cam wheel F4, will drive the latter, and with it the Jayer-shaft F5, and by means vof the :pitman-connection F6 between a wristpin f6 on said Ygear and cam wheel and a` crank f7 on the kend of the binder-arm shaft F7 will drive the flatter, and with it the binderf pinned to the shaft, so that the resistance G is a rock-shaft mounted in bearings outarm.

yside'of the .post-frame and above the trip-,3 shaftfand extending rearwardly to or .pastf the trip-cl-utch. At its Afront end, beneath the .gear and cam wheel, this rock-shaft has Aa crank g, 4connected by a link g with a leverVA Gr,pivoted to a lug g2 from 'the -pos'tframe` to the rear of the gear and cam wheel and in side of said wheel. This lever has a tang-ori heel extension g3, which strikes against the post-frame and prevents it froml being raised too high, and between its pivot and the point where the link is attached it carries a roller raised to its full height, thus holding the iinger mounted on the rock-shaft inward against the accumulating gavel or against the action of the binder-arm. When it reaches the straight reach 2 of the cam, the compressingfinger is permittedV to yield a little away from the binder-arm, that the trip-latch may escape the driving-dog as it comes round on its second revolution, as will directly be explained. When it gains the third reach 3., the compressing-{inger is again carried inward toits full extent, except as allowed to elastically yield, and is retained in such position until the knot is tied, when, nally, the last reach 4, which is cut away on an inward curve, allows the lever to drop, rocking the compressorshaft outwardly and carrying the compressing-finger down below the decking, that the bound sheaf may be disengaged bythe ejectorarms, which at that moment come around. ,'l`hen, regaining the fourth reach, the compressing-finger is reset, and at Athat moment the trip-clutch is thrown out of action, and the parts, with the exception of the packers, come to rest in t-he position shown in Fig. 4 in the drawings.

l lil is the compressor-finger, rigidly but adjustably secured to a block H by means of a bolt h and a slot 7L', or in other suitable manner. This block in turn is mounted upon the compressor-shaft, but instead of being pinned thereto it has a sleeve-bearing H2 thereon. Such sleeve is cut away for a little over halfl its periphery to form shoulders h2, and meets asecond sleeve H3, similarly cut away to form shoulders ha, thus leaving a space between the lapping shoulders of the two sleeves, so that the finger may have some play on the shaft,but will be stopped at each extreme of movement, this second sleevebeing pinned to the shaftA Around the ltwo sleeves is coiled a spring'HJ, one endr of which presses against a lug h4 on the block to carry the compressing-linger inwardly against the,

stop in that direction, and the other is capable of being sprung into engagement with anyone of a series of teeth 71.5, projecting from a angc on the forward sleeve, or that one which-is met by the trip-finger in rocking outwardly toward the outside stop maybe adj ustably determined. The inner end of the b lock is prolonged downwardly to form atrip-latcli, and at its `point has a lug or ange h6, which, whenever the trip-finger is in the position represented in'Fig. 4, comes into the path-of the second lug on 'thedriving-dogor the 'one opposed to that which engages lthe driving-lug, and, stopping the dog, causes it to swing on TOC IIO

its pivot,` thereby disengaging it from the driving -lug and unclutching the binding mechanism. Vheneveig however, grain has been packed sufficiently against the compressing-finger to rock it and the block which carries it upon the compressor-shaft to the limit or about the limit permitted by the shouldered sleeves, the block, or that part of it which forms the triplatch,will be drawn out of engagement with the driving-dog, and the latter will at once be carried by its spring into the path of` the driving-lug, and will be engaged by the irst one that next comes round, thereby starting the binding mechanism.

The vcompressing-iinger must be held up against the gavel while the latter is being bound; but should it retain the position shown in Fig. 4 when the driving-dog comes round at the completion of its first revolution the latter would be disengaged and the binder stopped before the band had been tied. Therefore the cam which controls the compressor shaft `is provided with the straight reach or cut-away part already mentioned, which at just this moment allows a slight outward movement of the compressing-finger sufficient W to carry the latch out of the path of the dog,

and then the succeeding concentric reach immediately resets the finger and holds it in position until the binding is completed.

K is the binder-arm or needle keyed to the binder-arm shaft and having the usual guardlinger K but its shank, instead of reaching almost directly from the shaft to the base of said finger in a curve, is formed with three curves 7c k 7a2, the first'of which is described upon an arc substantially concentric withthe point of the juncture of the other two,and has a guide-rib k3 embraced by flanges upon the free'endof a presser-arm K2, pivoted at said point of juncture. A coiled spring K3 is seated in a socket 7a4, formed at the point where the first and second curves meet, and this spring holds up ythe presser-arm toward a stop 765 on its guide-rib, so that it normally occupies about the position of the shank in the binder-arm commonly used in the field, andi` so, also, that when the binder-arm rises this i presser-arm will be opposite to the compressor-iin ger and will yield somewhat to the gavel, should it be of such size as to otherwise endanger breakage of the machine, thereby ob-= viatin'g the necessity of having a spring-link to hold the compressor-finger toits Work after the tripping action takes place.

The breast-plate L is of an ordinary form,

having a stop-finger Z in the cord-slot to tem-` porarily intercept the strands of cord and prevent their slipping past the tying-bill L', which latter is formed, as usual, with the rigid jaw Z and the pivoted jaw Z2, closed' at a certain point in its revolution by a spring'n cam L2, attached to the stock L3, in which the spindle of the knotter is mounted. A bevelpinion Z3 and delay-shoe Z, coactin'g with a gear-segment` Z5 and delay surface or rim Z6 on the tyer ca1n L4, serve to give this knetter a lsingle complete revolution and stop it, with its jaws trending' outward in the direction of the extended cord-slot, as indicated in Fig. ll, from which position it starts again in the next tying operation, sweeping the cord round slot and carrying it into the extended outer portion thereof. As it is not practically feasible to tie the knot in this single complete revolution, starting from the point indicated and ending at the same point, unless the ends v of the cord are partly carried around to meet lution, a holder-disk M is arranged in-con- Vacts against its lower edge, so as to stand .about perpendicular to the breast-plate and `at substantially right angles to the general ,trend of the cord-slot and on .that side thereof on which the tyer-bill is located, and is driven in such direction as to carry the cord-strands :down along the shoe from its free end to j ward its pivotcd end. 1 the purpose of the present description,is pro-4 vided with five notches m, and on its outer face is formed with bevel-teeth m', with cernotches correspond. On the innerv face and setout somewhat therefrom it 'carries a disk M2, having .five radiating knife-bladesfn, one of which comes slightly behind each of vthe to la certain angle round the tyer-spindle'by the revolution of the holder-disk the blade behind the notch in which the strands are held will be brought against them and sever them between the knotter and holder.

The pivot m3 of the holder-disk and of' its accompanying knife is located in a plane farther removed from the cord-slot than is the carrying the cord around and practically on the further side of the tyer-eam, and it is Atherefore driven from the farther side of. the tyer-cam, or the side reverse to that which drives the knetter.
